mybatis逆向工程之maven工程

Posted 2020-10-20 挑战者V

maven工程与动态web工程存在差异，不过大体是相同的

注意：运行成功后记得refresh刷新下，否则看不到

一、在pom文件中进行如下配置

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
	<modelVersion>4.0.0</modelVersion>
	<groupId>cn.mybatis.generator</groupId>
	<artifactId>mybatis-generator</artifactId>
	<version>0.0.1-SNAPSHOT</version>

	<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
	</properties>

	<dependencies>
		<dependency>
			<groupId>mysql</groupId>
			<artifactId>mysql-connector-java</artifactId>
			<version>5.1.35</version>
		</dependency>
		<dependency>
			<groupId>org.mybatis.generator</groupId>
			<artifactId>mybatis-generator-core</artifactId>
			<version>1.3.2</version>
		</dependency>
	</dependencies>


	<build>
		 <pluginManagement>
            <plugins>
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-compiler-plugin</artifactId>
                    <configuration>
                        <source>1.8</source>
                        <target>1.8</target>
                    </configuration>
                    <version>3.3</version>
                </plugin>
                <plugin>
                    <groupId>org.mybatis.generator</groupId>
                    <artifactId>mybatis-generator-maven-plugin</artifactId>
                    <version>1.3.2</version>
                    <dependencies>
                        <dependency>
                            <groupId>mysql</groupId>
                            <artifactId>mysql-connector-java</artifactId>
                            <version>5.1.35</version>
                        </dependency>
                    </dependencies>
                    <configuration>
                         <!--配置文件的路径-->
                         <configurationFile>src/main/resources/generatorConfig.xml</configurationFile> 
                        <overwrite>true</overwrite>
                    </configuration>
                </plugin>
            </plugins>
        </pluginManagement>
	</build>


</project>

 

二、在src/main/resource目录下新建配置文件generatorConfig.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
  PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
  "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<generatorConfiguration>
	<context id="test" targetRuntime="MyBatis3">
		<plugin type="org.mybatis.generator.plugins.EqualsHashCodePlugin"></plugin>
		<plugin type="org.mybatis.generator.plugins.SerializablePlugin"></plugin>
		<plugin type="org.mybatis.generator.plugins.ToStringPlugin"></plugin>
		<commentGenerator>
			<!-- 这个元素用来去除指定生成的注释中是否包含生成的日期 false:表示保护 -->
			<!-- 如果生成日期，会造成即使修改一个字段，整个实体类所有属性都会发生变化，不利于版本控制，所以设置为true -->
			<property name="suppressDate" value="true" />
			<!-- 是否去除自动生成的注释 true：是 ： false:否 -->
			<property name="suppressAllComments" value="true" />
		</commentGenerator>
		<!--数据库链接URL，用户名、密码 -->
		<jdbcConnection driverClass="com.mysql.jdbc.Driver"
			connectionURL="jdbc:mysql://localhost:3306/blog" userId="root"
			password="1234">
		</jdbcConnection>
		<javaTypeResolver>
			<!-- This property is used to specify whether MyBatis Generator should 
				force the use of java.math.BigDecimal for DECIMAL and NUMERIC fields, -->
			<property name="forceBigDecimals" value="false" />
		</javaTypeResolver>
		<!-- 生成模型的包名和位置 -->
		<javaModelGenerator targetPackage="cn.blog.model"
			targetProject="target">
			<property name="enableSubPackages" value="true" />
			<property name="trimStrings" value="true" />
		</javaModelGenerator>
		<!-- 生成映射文件的包名和位置 -->
		<sqlMapGenerator targetPackage="cn.blog.mapper"
			targetProject="target">
			<property name="enableSubPackages" value="true" />
		</sqlMapGenerator>
		<!-- 生成DAO的包名和位置 -->
		<javaClientGenerator type="XMLMAPPER"
			targetPackage="cn.blog.mapper" implementationPackage="cn.blog.service.impl"
			targetProject="target">
			<property name="enableSubPackages" value="true" />
		</javaClientGenerator>

		<!-- 要生成哪些表 -->
		<table tableName="`post`" domainObjectName="Post"></table>

		<table tableName="`posttag`" domainObjectName="PostTag"></table>

		<table tableName="`tag`" domainObjectName="Tag"></table>

		<table tableName="`type`" domainObjectName="Type"></table>


		<table tableName="`typetag`" domainObjectName="typetag"></table>


	</context>
</generatorConfiguration>

 

三、右击进入run as 点击maven build  如下图输入:mybatis-generator:generate

 

四、出现如下图所示表示成功
